Yes, but the thing is, there is absolutely no reason to be struggling in low-level dungeons. I mean the guy complaining hasn't even hit level 50 yet, and he's already complaining about the pacing that tanks are setting and how he can't keep up. and generally in low-level dungeons you aren't doing these across the map pulls like in level 60 dungeons it usually goes one pull at a time, which doesn't have a substantial amount of damage to really drop people if you're doing your job and healing.
